So I created this deck after another mage whipped an 18/18 C'thun out on me during round 11 and proceeded to use my ass as an anvil to forge 10,000 horseshoes. It was brutal.

I'm broke and I've spent less than $10 on card packs, won several, etc. So I'm not card rich and I  threw in as many C'thun buffs/boosters as I could while still making the rest of the deck functionally able to battle it out to round 10. Usually I end the match at round 10 (round 9 if I got the coin this match).

Mage standard cards plus C'thun is really all it is, and it's worked damn good for me so far. I started at 2 taunts, found 4 made things much easier, but I'm going to tinker with that because ideally I'd like to have only 2 or 3. Because Frostwolf Grunt is really such a dildo, his sole purpose is to soak up one or two enemy cards early on.

Cantrip cards are important. I wanna flip those cards over and get C'thun all buffed up and scary (it has the added benefit of making your opponent nervous and eager to try burning you down before you can squirt C'thun out and get biblical)
So Azure Drake is great. 
Arcane Intellect ...no shit, sherlock

Might do well to swap out one of the more situational cards like Frostbolt or the possibly unnecessary Twilight Geomancer with Acolyte of Pain.

Unrelated note: I had just crafted two Knife Juggler and had to use them immediately so they went in here and they are just great. My favorite thing to do is on Round 6, if the gods are with me I'll have two of those in my hand with a Frostwolf Grunt ... and you can't spend 6 mana any better. Throw down 1 Knife Juggler, then Knife Juggler #2, followed by Frostwolf Grunt to hopefully give them some safety next round...it's a fun play with a pleasing amount of 'charge' damage.

I know this is a simple noob deck, but there's no denying my noobitude so I'm just embracing it with this long explanation of an obvious selection of cards. Having said that, I'd be very happy to hear what improvements anyone reading this would make, keeping in mind that it's a budget deck so improvements from new cards under 500 or so dust would be a good range.
